1,4-dioxane by 522 column modifications
Posted: Tue Nov 20, 2018 6:24 pm
Hi all,
Has anyone attempted to use a thinner film than 1.4 um for 1,4-dioxane by EPA 522? We are setting up a new instrument (6890/5973) to run PAH by 8270 and 525. If 522 by a 1.0 um column is feasible, I'd like to give it a shot as our subcontract lab for 522 is quite slow. Otherwise we'll stick with 0.25 um and enjoy the shorter run times for 525/8270.
Thanks.
